COUPLING FUR HAY-LOADERS.

To all whom it may concern:

Be it known that I, WILLIAM Bisi-tor, of the town of Grand Valley, in the county of Dutferin, Province of Ontario, Canada, have invented certain new and useful Improvements in Couplings for Hay-Loaders, of which the following is the specification.

My invention relates to improvements in hitching devices for interconnecting a hay loader and wagon and the object of the invention is to provide a simple quick operating device for expeditiously hitching the hay loader to the wagon and by which the operation may be done with a minimum amount of labor, and it consists essentially of a tongue secured to "the hay loader having aV broadened outer end and supplemental tongue pivoted beneath the aforesaid tongue so as to have both a vertical and a horizontal swing, an arrow headed piece pivoted to the outer end of the supplemental tongue, locking means designed to hold the supplemental tongue in its raised position, a co-acting member secured to the rear end of the wagon comprised by a pair of wings set in a V- shaped form having inclined top edges and an opening separating the approaching ends of the wings, and a releasing means whereby the supplemental tongue may be released so as to drop on to the inclined edge of the wings when the wagon is backed into hitching position beneath the supplemental tongue and a hinge supporting leg connected to a suitable frame work depending from the tongue of the hay loader as hereinafter more particularly explained by the following specification.

Figure 1, is a general perspective view of a portion of a hay loader and rear end of a wagon with my device shown in position ready to be brought into operation. Fig. 2, is a longitudinal sectional detail extending through the hitching device showing the same in connected position. Fig. 3, is a plan view of my hitching device as shown in Fig. 2 of the drawings.

In the drawings like letters of reference indicate corresponding parts in each ligure.

A is the loader, A the supporting wheels, A2 the reel, A2 the side bars of the elevating portion of the loader and A* the side standards of the loader'.

B is a cross bar extending between the side standards A4 of the loader and connecting them together.

length of the cross bar B and extending outwardly at right angles thereto. r)lie tongue B 1s provided with a broadened outer end IB2 for a purpose which will be hereinafter explained.

v B3 and B* are upper and lower braces` connecting the outer end of the tongue B with the top and bottom of the side standards A4.

C are brackets secured beneath the rear end of the tongue and C is a supplemental tongue pivotally connected between the brackets C so as to have a vertical swinging movement therein.

C2 is an extension to the supplemental tongue C and connected to the supplemental tongue C by a hinged connection C3 by means of which the extension C2 is capable of swinging movement in a horizontal plane. The outer end of the extension C2 is provided with an arrow headed portion C2 which is pivotally connected in a notch C5 formed in the outer end of the extension C2.

D is a frame `comprising the angularly depending side bars D, the front ends of the side bars being provided with the reduced threaded portion D2 which extends through the flattened end B2 of the tongue B and in which they are secured by the nuts D3. The rear end of the side bars are connected to each side of the tongue B in proximity to the rear thereof. From the angle of the side bars D the cross bar D4 extends connecting the side bars D together. rl`he cross bar D4 is provided with depending lugs D5 through which extend bearing pins DG.

D7 is a supporting leg on the upper end of which is secured the outwardly extending bars D2 provided with holes at the inner end thereof through which the bearing pins D extend so as to ferm a swinging connection for the leg D7 on the cross bar D4.

E is a U-shaped bracket depending from the tongue B to each side of the supplemental tongue C.

E are supplemental bars extending from each side of the U-shaped bracket E to the side bars D of the frame D.

F is a lever pivotally connected at its inner end to the supplemental tongue C and F is a projection extending from the front portion of the lever F.

F2 is a spring plunger secured in a casing F3 secured to the top of the tongue B. The plunger F2 normally extends beneath the projection F so as to hold the lever F and the supplemental tongue pivotally connected thereto in their upper position.

F4 is a cord connected to the spring plunger F2 and extending forwardly over the wagon to a suitable position so as to be operated by the driver.

G is a wagon provided with a rearwardly extending portion G to which is suitably secured a bracket G2. The bracket G2 is provided with upwardly extending wings The wings G3 are arranged in a V- shaped position with the apex of the V extending rearwardly. The upper edge G1 of the wings G are inclined from inside to outside as shown in the drawings.

G is an opening 'eparating the inner ends of the wings and to each side o-f the opening and extending from the wings G3 are supplemental projecting ribs GR GS are bearing rollers Journaled 1n suitable lugs G9 extending from the brackets G2. These rollers serve to support the broadened end of the tongue B when the hay loader is hitched to the wagon.

I-Iaving now described the principal parts involved in my invention I will briefly de- Scribe the operation of the same.

lVhen hitching the hay loader to the wagon the driver backs his wagon toward the hay loader so as to bring the wings G3 of the wagon beneath the outer end of the supplemental tongue C. He then pulls on the cord F4 so as to withdraw the spring plunger F2 from beneath the projection F of the lever F. By this means the supplemental tongue is freed and allowed to drop vertically downwardly into the opening G5. If the wagon is not backed so as to bring the opening G5 directly in alinement with the supplemental tongue G, such supplemental tongue falls on one of the inclined upper edges G4 of the wings G3. By means of the hinged connections between the forward eX- tension C2 of the supplemental tongue C such forward extension swings laterally and is guided by the inclined top edge GAL into the opening G5. The driver drives the wagon forwardly and the arrow head GL engages with the engaging rib GT thereby connecting the supplemental tongue to.l the wagon. Upon the further movement of the wagon the hay loader is drawn forwardly so as to release the supporting leg D7 from the ground thereby allowing the tongue B to drop until the broadening outer end B2 rests upon the rollers GS when the mechanism will be in position shown in Fig. 2 of the drawing. I-Iitherto when it has been necessary to connect the hay loader with the wagon, the wagon is backed so as to bring the rear thereof as near as possible to the tongue of the hay loader. It is very seldom brought into correct position for connecting and it is therefore necessary for the driver to dismount from his wagon raise the tongue of the hay loader and draw the hay loader over so as to be brought into position to connect with the wagon. This of course, is a very laborious operation and is dispensed with by the use of my hitching device. By the use of my hitching device it. is only necessary to bring the wagon in close proximity to the tongue and not in direct alinement therewith before the hitching can be aecon'iplished as has already been shown. The supplen'iental tongue C is carried into the central and correct position by the inclined upper edges of the wings G".

From this description it will be seen that I have devised a very simple device whereby the hay loader may be easily and quickly connected to the wagon without the driver dismounting from his seat or exerting any unnecessary labor. 3y providing a broadened outer end to the tongue B which rests upon the roll-ers GS and also by the use of the hinge connections between the extensions Gl and the supplemental tongue C I provide means whereby the lateral swing of the hay loader is allowed for and at the saine time giving a solid bearing surface for the end of the tongue.

IVhat I claim as my invention is:
